To all whom it may concern:

I Be it known that I, SIMEON CorsKY,asubject of the King of Great Britain, and residing in the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and use.- ful Improvementsin Machines for Screwing Sockets and the like; and I do hereby declare that the following is a full, clear, and exact description of the same The invention relates to a machine for screwing sockets and the like and more particularly brass sockets on shells and the object of the invention -is to devise a'machine which will screw the brass sockets on shells rapidly, thereby economizing in the cost of manufacture and saving hands to do it.

A further object is to devise a machine that will screw these sockets tightly .and

once the machine has been set,'it is so easy to operate that it can be worked by'a boy or unskilled person.

The invention will be "fully understood with the aid of the accompanying drawings in which Figure 1 is a side elevation of the ma chine. Fig. 2 is a longitudinal cross sectional view of the machine. Fig. 3 is a top view of the machine. Fig. 4 is atop view of the machine showing the worm and gear in section. V

Like numerals of referenceindicate corresponding parts in each'figure. Referring to the drawings, 1 is a casing having an inwardly projecting flange 2 and supporting legs 3 and lis a coveringplate having a central orifice 5.

6. is a supporting table on which is secured the said casing 1.

'7 is a chuck having the central bore 8, tapered at its outward end 9, and 10 is an outwardly and downwardly projecting stub, threaded at11.

12 is an orifice through said projecting stub 10 and 13 is an outwardly projecting flange intermediate of the height of said chuck 7 abutting under the flange 2 in the casing 1 and secured thereto.

14 is a gear rigidly secured to the collar 15, said collar being loosely mountedon the upper end of said chuck 7 and restmg on the flange 2 and 16 is a stop collar secured around the outward end of the chuck above said collar 15.- 17 are posts or lugs secured to said collar 15 and outwardly projecting therefrom engaging'thepawls- 18 which are pivotally mounted on" the ring 19 at 20, said pawls having the eccentric heads 21 which slightly pro ect inwardly through the central orifice 22 in the ring 19.

v 23 is an inner chuck loosely fitting in said chuck? having at its outward end a corresponding tapered end 24 and- 25 is an orifice in which passes the tube 26, said tube having the head 27 projecting inside said. inner chuck and thread 28 on which is threaded the nut 29, thus firmly clamping the bottom of theinner chuck, the other end of said tube being of a smaller diameter and also threaded at 30.

31 is a hand wheel having the partial central bore 32 one end of which is opened and inwardly threaded at 33, said thread engaging the thread 11 on the lower end of the chuck 7, the other end being provided with an orifice 34 and 35 is a collar mounted on saidv smaller diameter tube, abutting against the shoulder formed by thelarger diameter of the said tube 26' andrestingagainst the bottom of said bore 32 and 36 isa nut engaging the thread 30 on the end -.'of the tube 26 and rigidly securingthe hand wheel 31 on said" tube 26. The said inner chuck-23' is longitudinally slotted atdifi'erent intervals therearound so that it may have some elasticity and therefore grip the 'shell 37 more firmlyand 38 is a circumferentialdepression intermediate of the length of said chuck 23, so as to'avoid friction.

' 39 is a bushing having a central perf0raupper end of the shell adapted to protect =ti0n 'of identically the same shape as the th'e copper'bandon the shell, also tolock said shell in the chuck 23.

40 is a rod in said tube 26 and 41 is a --foot lever, fulcrumed at- 42 and actuating said rod upwardly to push the shell out of the chuck when the cap-43 has'been screwed.

Theshell is first placed in the chuck and rests on the head 27 of the tube 26. in the bottom of the inner chuck 23, the bushing 39j-is'thcn placed on said shell between the side of said chuck and shell and the hand wheel 31 is turned thereby pulling the chuck 23 downwardly and locking the shell 37.

44 is a worm mounted on the shaft 45 engaging the gear 14 and 46 is a pulley mounted on one end of said shaft 45 the other end being suitably supported by the bearings 47 in the side of the casing 1.

48 is a lever pivotally secured to one end of the shaft 49, said shaft being supported by the bracket 50 secured to the casing 1 below the worm 44 and loosely revolving therein.

51 is a bracket secured to the other end of said shaft 49, shown in dotted lines, supporting the tightening pulley 52 which contacts with the belt 53 when the lever 48 is pulled inwardly thereby regulating the driving power of the machine at will.

After the shell has been set in the chuck as described above, the threaded. cap 43 is placed on the end of the shell 37 and the ring 19 is placed on said cap 43, the central orifice 22 engaging one side of said cap. The lever 48 is pulled to give the driving power to the machine, and the worm mounted on the shaft 45 rotates the gear 14, the gear 14 rotates the collar 15 and the posts 17. In revolving, the posts or lugs 17 come in contact with the pawls 18 and slightly tip them which causes the eccentrics 21. 'to engage the sides of the cap 43 and lock same. When the operation of screwing the cap is terminated, the ring 19 and the bushing 39 are removed and the hand wheel unscrewed, thereby unj amming the shell from the chuck 23 and the foot lever 41 is pressed, pushing the rod 40'forward and lifting out the shell from the chuck.

The operation of the invention, as will be seen, is most simple and it does not require skilled hands to work this machine.

It must be understood that the constructional details of the herein described invention can be modified, if found desirable, so long as I do not depart from the invention as claimed in the following claims for novelty.

Vhat I claim is: I 7
